My invention relates to multi-ratez'or plucontrolling systems therefor.

.My inventionv has foran object toprovide a switching system formulti-rate meters, whereby lthe day control ris changed or madenon-effective during a portion of the'week, for example, during theSunday rest period.4

In my invention, the week control oper-'f ates switches that render .theusual automatic day control non-'eective and place a manualY L theSunday rest period, the tariff switches 21 and;` 22 are madenon-effective.

day lcontrol in proper circuit relation for control purposes. t

,My invention thus provides means whereby any one of a plurality ofrates may be made operative during the Sunday rest period, ac cording tothe seasonor operating conditions. My invention also permits twoyormorerates to be made operative duringthe Sunday rest` period but atdierent times than'fduring. working days. y The features ofmy-inventionwhich are be-J lievedfto 'be' novel and patentable vwill bepointed out in the claims appended hereto.

For .a better understandingvr of' my Vinvention, reference is. made, inthe following vdescription, to the accompanying drawings', in which,

.,...Figure 1 is a diagrammatic view of my invention applied to yatriple-tariff meter;

Figs. 2, 3 and 4 are similar views of modilications of my invention,.and

Fig. 5 is a schematic perspective view of .a,multi-rate` meterconstructed in accordance with my invention.

Figs. l to 3, inclusive, and 5 show switch systems for triple-tariffmeters provided,4 with two magnet cores 4 and' 5 providedY respectivelywith operating coils 1 and 2, in which one tariill is imposed whenthecoil 1 isenergized, the second'tarif'f whenV the coil 2 is energized,and the third tarill when both coils 1 and 2 are deenergized. f

, v.Referring to'Figs. 1 and 5, theloperating coils 1 and 2 are inseries circuit with tariff switches 21 and 22 that are, in turn, inseries circuit with a locking switch 30. The 'tariff switches 21V and 22are actuated by control Spectively, on the day disc 101 in a certain .isan idle contact.

The week disc 106als'o controls a lbridging switch 34that is in 'seriescircuit with a changeoverdevice 35.' The latter device has rthreevcontacts 31, 32 and l33, ofuwhich the' contact 31 is connected to thecoil 1 and the# l contact 32, to the coil 2, while the contact 33,;
